Approval is all he needs, really, and the spark of joy it brings to Blake knowing Geralt has nothing bad to say probably gives away that he's come to understand the code: No news is good news when it comes to the Witcher. Hell, a grunt of dismay might actually feel like a gold star to some, in fact, although the younger man thinks it's as much for show as it is for his companion's sanity; too many people equals too much exposure, and under those circumstances, even mild gripes or compliments could be taken to some level of detriment.

"Geralt, you can't afford me," Blake flippantly snipes on his way out. He's got a bath to take and having been relieved of some of the guilt, there's no reason not to get on with it.

Still, a second after leaving, he peeks back for only a moment to say, "But I'm not saying no." Far be it for him to pretend he's not a little bit flattered.
